Doing a movie is a stressful thing. You spend months of you life focusing into that one project, and I want to make sure I do something I really like or I'm really passionate about.

I don't make comparisons between any movies. I compare characters. All my actions, performances, all my films, they are driven by the characteristic. If I'm playing a cop, then I give him a particular style - I may not know that style, but as an actor I have to be responsible to do your homework and do your research and training and stuff like that.

A lot of people don't realize, when you are acting in a martial arts film, you're not just performing martial arts. You're not just performing martial arts. You're actually acting as much as any other actor.

I always used to wonder why American actors were getting fat, then I made a U.S. movie. I'm seeing all the food every day, and there's lots of waiting around because making an American movie is very slow.

For me, shooting, editing, and scoring rely on rhythm.

There's a lot of thinking when you choreograph something. You're not just choreographing some bodies, arms, legs flying around to look cool. It's a lot more complicated and sophisticated. You also have to deal with the connection of the whole film, so when I choreograph, I think of the movement itself, the camera angles, the characters.

Like any other actor, I draw on life experience.
